CHEYENNE, Wyo. (AP) - The first phase of a cleanup project at a former nuclear missile site east of Cheyenne is complete, but it will be about a year before officials know if it is working.

The Wyoming Tribune Eagle reports (https://bit.ly/2eeImo6 ) that during the last few months CB&I;, a contractor hired by the U.S. Army Corps of Engineers, has injected millions of gallons of a solution containing bacteria into the ground of the missile site near Burns with hopes that the bacteria will break down trichloroethylene, a cancer-causing chemical, in the groundwater.

A second phase, to begin next year, will install a “treatment zone” near the front of the TCE plume to try to stop it from advancing.

Army Corps officials say they will regularly monitor the plume in the coming months.
